Does anyone know of a salvage yard for compact tractors? I would like to add an auxiliary hydraulic port to my 7235. I plan on putting in a splitter valve to operate the hydraulic lift on my retrofit mower deck, and a rear port for my wood-splitter. I saw the valve I'm looking for on line for $1200.00! That's CRAZY! I know these tractors were built by Mitsubishi and are the same as Mahindra save for the looks. I was hoping to find one in a grave yard I could get on the cheap. Thanks all, Denny

Do you have a rear port now? Some machines have a single rear port which operates the three point hitch, if this is the case you may not absolutely need the spitter... I checked into it too.- Big bucks. ....

Go to http://www.surpluscenter.com/ and run a search for 1tem # 900 and 9-4128 or 9-6131. I don't know what kind of splitter valve you are looking at.
I tried to run my log splitter off of a Kubota L3010 and GPM was to low and it was way to slow, so I went back to my PTO. I use a Cross series 40 pump that I geared up 3:1 and run my tractor RPM around 1200 to 1500 RPM. I save on fuel now, before I had a bigger pump but had to run at 2500 RPM and I didn't like the engine running free at that RPM when it wasn't working the splitter. It's just about right now.

DZLDenny,

Leejohn is correct. I don't believe you'll have enough flow to operate a log splitter with your tractor.

A log splitter, with a 4 inch diameter cylinder, 24 inches long, requires 12-14 gallons per minute to operate efficiently.

With 12-14 gallons per minute, you'll be able to split a log and return to the start position in about 20 seconds. At only 6 gallons per minute, that time will double to 40 seconds.

I'm guessing that your tractor will only put out about 4 to 5 gallons per minute......which will increase your cycle time to over 1 minute. The cylinder on your splitter will seem like it's not even moving.

Before you spend the time and money on this project, I ask that you look into the flow rate from your tractor's hydraulic pump.

Now.....your tractor will easily handle the mower cylinder. You won't have any problem there. The log splitter is a different story. It will split wood, but you'll be able to drink a cup of coffee between logs.

This is the primary reason why small tractors don't have remote hydraulic ports installed on them from the factory. These little tractors simply don't have what it takes to do that type of work.

You do have another option, however. You can purchase a Prince PTO Pump, and then run your splitter off of your PTO powered pump. This will require that you build an oil reservoir on your splitter, which isn't a big deal. If you go this route, make sure you get the proper PTO pump for your tractor. You can match a Prince pump to your tractor by the horsepower rating of your PTO shaft, which is generally three to four less than your engine's horsepower.

If you have any questions, feel free to ask. There are many of us here who are always happy to help.

Joel

No rear port on the tractor now. all of the hydraulics for the 3pt are internal. nothing to tap into there. It seems as though it would have plenty of flow if you look at the speed that the loader goes up and down. I know that the volume of 2 2" cylinders is not that of a 4", but I'm running the splitter off of my 154 loboy with no trouble. Maybe a power beyond at the loader line? I've seen the exploded view of the aux valve assy, and it has 3 ports built into the system. If I knew which of the three ports was supply, return, etc, I would tap into the side of the rear end where the aux valve mounts and plumb to a valve like they carry at surpluscenter or the local supply house.
Being a machinist by trade I'm not afraid to build my own or adapt something. I just thought that the salvage yard has been a cheap out for parts in the past. None of them in my area carry compact tractors though. Where do these things go when they poop out? Thanks for the replies. Denny ....

use your 2 short hyd. lines that are between your loader valve and power blosc-quick disconects. ....
